I would like to distinguish between NTP version 3 or version 4 and NTP version 2.
I need to be sure that one equipement is really able to work with NTP version 3 or 4.
What parameters or fonctionnality should be supported by this equipment in order to validate that it is really using NTP version 3 or 4 instead of version 2.
Is there some particular fields in the NTP version 3 / 4 messages that can be check using wireshark?
Thanks a lot in advance
